Abstract:
Embodiments of the Lighted Ladder are comprised of a ladder; a plastic housing; one or more LED strip lighting; a cordless battery mounting means; a battery; a controller housing; a control interface; power wiring; potentiometer wiring; and motion sensor wiring. The ladder is weight-balanced by placement of the battery mounting means, the battery, and controller housing in a low position on the ladder. The battery mounting means is designed to accept a cordless tool battery. The battery mounting means is designed to accept a commercially available battery of at least 12V and at least 3.0 Ah. One plastic housing is located on each of the vertical front rails. Each LED strip lighting can illuminate an angular range of 120 degrees (120) creating a total illumination range of 300 degrees (300).
Abstract:
A ladder system is disclosed which allows for stabilizing a ladder on multiple surfaces without the need for a second person or a great deal of setup time. The collapsible ladder system includes a larger ladder section and a smaller ladder strut section which are pivotally connected at a point which is at or below the midpoint of the larger ladder section. The larger ladder section and smaller ladder strut section are connected by a rigid adjustable linkage, or spreader, at a point that is below the pivotable connection. The ladder further includes a means for stability on a variety of surfaces. At the ground contact point, the point where the ladder side rail ends and the ground meet, there are adjustable gripping feet, which can be independently or in combination vertically or angularly adjusted for maximum stability.
Abstract:
Elevated work platform apparatuses, as well as associated methods, are provided. In one particular embodiment, an elevated platform apparatus is provided comprising a first assembly having a pair of rails coupled with a plurality of rungs, a second assembly hingedly coupled with the first assembly, a platform pivotally coupled with the first assembly and configured to extend to, and engage a portion of, the second assembly. The apparatus further includes a cage associated with the platform. The cage may include at least one bar and at least one gate, the at least one gate being configured to swing in a first direction upon a user stepping on to the platform from the first rail assembly, and then swing back to a closed position after the user is standing on the platform. Platform includes a toe-kick structure that is collapsible relative to the deck of the platform.
Abstract:
Ladders and related methods of using and manufacturing stepladders are provided. In one embodiment, a stepladder is provided that comprises a first assembly hingedly coupled with a second assembly. The first assembly has a pair of spaced apart rails pivotally coupled with one or more rungs. The second assembly includes a pair of space apart rails with one or more bracing members extending therebetween. The first assembly and second assembly are configured to be displaced relative one another such that the stepladder is selectively positionable between a first, deployed state and a second, collapsed state. Upon rotation of the two assemblies relative to one another into a stowed condition, components of the second assembly engage undersurfaces of the rungs effecting rotation of at least a portion of each rung relative to the rails of the first assembly.
Abstract:
A ladder including a first stringer and a second stringer spaced transverse from each other is provided. Each of the first and second stringers defines a channel and includes a plurality of crosspieces disposed in the channels of the first and second stringers. A plurality of rungs are spaced along and coupled between the first and second stringers. Each of the rungs has a horizontal portion and a vertical portion extending from the first stringer to the second stringer. A plurality of ribs are spaced along and coupled between the horizontal and vertical portions of the rungs.
Abstract:
A ladder support assembly including a base frame having first and second ends and a pair of pivot supports extending from the base frame which support a rod configured to pivotally support a ladder relative to the base frame. A pivot frame is pivotally mounted to the base frame and is biased away from the base frame. A bracket assembly is pivotally mounted to the pivot frame and includes a pair of bracket plates. Each bracket plate has an inner flange and outer flange with a ladder rail receiving area between the inner and outer flanges. The ladder receiving area is configured such that the bracket plate is slidable relative to a respective ladder rail received therein. A crank assembly includes a spool rotatably supported on the base frame and a cord wound about the spool with a free end of the cord connected to the bracket assembly. Rotation of the spool in a first direction takes up the cord and causes the pivot frame to pivot toward the base frame, thereby raising the ladder toward a raised position. Rotation of the spool in a second, opposite direction causes the cord to be let out and the pivot frame to pivot away from the base frame, thereby lowering the ladder toward a lowered transport position.

Die Erfindung betrifft eine in eine Transportkarre umwandelbare Klappleiter mit einem Leiterteil (1) mit Stufen (2) oder Sprossen, welches im oberen Bereich ein erstes Schwenkgelenk (3) aufweist, an dem schwenkbar ein Stützteil (4) ansetzt, dadurch gekennzeichnet, dass das Stützteil (4) aus mindestens zwei Teilstützteilen (5, 6) besteht, die über ein zweites Schwenkgelenk (7) miteinander verbundenen sind, so dass das untere Teilstützteil (6) in Richtung des Leiterteils (1) schwenkbar ist und im Bereich des zweiten Schwenkgelenks (7) mindestens ein Karrenrollmittel (8) am Stützteil (4) eingerichtet ist, und wobei an dem dem zweiten Schwenkgelenk (7) gegenüberliegenden Ende (9) des unteren Teilstützteils (6) ein Mittel zum lösbaren Verbinden (10) des unteren Teilstützteils (6) mit dem Leiterteil (1) eingerichtet ist, so dass bei Verbund des unteren Teilstützteils (6) mit dem Leiterteil (1) ein geschlossener Tragrahmen (11) entsteht, der auf dem mindestens einen Karrenrollmittel (8) bewegbar ist und bei dem das Leiterteil (1) den Lasthalter (12) zur Aufnahme einer Last (13) bildet.
Abstract:
A step ladder includes a first assembly having a first pair of spaced apart rails, a second assembly having at least one rail, and a top cap coupled with the first assembly and the second assembly. At least one of the first and second assemblies may be pivotally coupled with the top cap. The first assembly includes a plurality of rungs coupled with the rails and may exhibit a vertical spacing of a first distance between adjacent rungs, a vertical spacing equal to the first distance between the lowermost rung and a supporting surface (e.g., the ground), and a vertical spacing between the uppermost rung and the top cap that is greater than the first distance. In one particular embodiment, the vertical spacing between the uppermost rung and the top cap is twice the distance of the first distance.
Abstract:
Echelle extensible repliable dont son montant Rep. l unique situé dans son plan de symétrie constitué d'un ensemble de segments Rep.2 et segments adjacents Rep.3 de même longueur, chaque segment et son segment adjacent correspondant étant articulés entre eux en leur milieu, les segments consécutifs étant articulés en leur extrémité, les distances entre deux articulations successives étant toutes identiques, la mise en œuvre de l'échelle se faisant en déployant manuellement les parallélogrammes, jusqu'à obtention de l'extension maximale, tandis que la mise en configuration de stockage s'effectue suivant la séquence inverse. Les barreaux Rep.4 situés soit au niveau de l'articulation médiane de deux segments en vis-à-vis, soit à chaque articulation de deux segments successifs sont disposés en face avant de l'échelle, les articulations entre deux segments successifs situées en face arrière de l'échelle ne possèdent pas de barreaux, chacun des barreaux Rep.4est fixé en son milieu dans le segment Rep2 et articulé dans son segment adjacent Rep.3. Le dernier barreau inférieur est lié à un élément assurant l'appui au sol tandis que le dernier barreau supérieur est lié à un élément équipé de patins pour appui en paroi afin d'assurer la stabilité de l'échelle. Un crochet escamotable Rep.l 1 verrouille l'ensemble des parallélogrammes, De plus, cette échelle extensible repliable, permet, par son déploiement partiel ou par suppressions de certaines liaisons articulées avec adjonction de barres stabilisatrices de réaliser très simplement un pied de table à hauteur variable, ou bien une table complète à hauteur variable, ou bien encore un escabeau repliable.
